Hi Francois, > From: franc...@tekwire.net> > May I suggest to extend your proposal to is_null() with the same logic ? If we were to do the same with is_null(), then would it not be best to do it with all the is_*() functions? I would be more than happy to cater for those functions as well, though their usages seem a lot less common. What does everyone else think? > > François
Thanks, Tom
